To all whom it 'may concern:

Beit known that I, KARL H. HANSEN, a residentv of Pittsburg, in the county of Allegheny and State of Pennsylvania, have in vented a ne'w and useful liiiprm-enient in Dump-Cars; and l do here-by declare thefol' lowing to be a full, clear, and exact description thereof.

' My invention relates to dump cars.

The object of my invention is to )rovide a ear of this character which is lowuiltand which may be readily dumped and brought back to position, while at the Sametime to provide mechanism by inems of which .the car may be locked in its normal position and released from 'either- `side, the car being automatically locked upon its return after dumping' To these ends my invention comprises the novel features 'hereinafter set forth and' claimed.

In the accompanying drawing Figure 1 is an end elevation oany improved car, dotted lines showing the car in dumping position; F i0. 2 is a side elevation partly in section.

n thedrawings the numeral Z designates a suitable truck frame which may be built up of angle-bars, gusset plates, etc., suitabl This truc frame is mounted upon the wheels 3. Struts or guides 4 are riveted to the angles 6 of the truck frame and said struts forni guides lfor the cradles 8 secured to the ends of the car body 9. The angles 6 are carried by the'up- 4rights 5. 'lhe cradles S are provided with the pins or projections 1() which are adapted to engage the downwardly extending inclined arms of guides or struts. 4. Angles 7 on the angle bars 6 forni stops for the pins 10 when the car is duin ved. At each end of the car atopposite si 'es thereof are the levers 11 which are pivoted at 12 in brackets 13 on the.

guide bars4. l The pins 1() engage. the inner ends of the levers 11 so' as to lock the car body in its upright or normal position. v'i lie weight of the long arinsof the evers 11 holds the levers down normally in the position shownin full lines in Fig. 1. The cradles 8 are formed with the cycloidY or compound curve 14 and said cradles rest on the top of the angle bars 6. The cradles have the teeth 15 formed thereon which are adapted to engage the openings 16 in the angles 6.

When the car is loaded and it is desired to dump the saine to. the Vleft the operator the lever 11 and throws it to the upright position iiidicated'iii dotted lines Fig. 2. This releases the pin or enlargement 10v whereupon the operator by pushing on that side of the car adjacent to hiiii is readily standing on the opposite side ofthe car lifts i able to throw the car into the dumping position the projections, 10 are guide by the downwardly' extending inclined arms of the guide bars 4 as indicated in dotted lines lig. 2 until said .projections come incontact' with the stops 7. The lever 11 will be in the path of the in 1() and will be moved to its normal position after the car bod f has been freed, and when the car bo y is brought back to its normal position after dumping the lug 10 uiill engage'theinner end of said lever and will lift said lever suiiiciently to allow said lug to assume the position indicated in Fig. 1, whereupon the weight of the long arin of said lever 11 will cause said lever to assume its normal iosition and so automatically lock the car ody in its` upright position.

Y sitioii, the cradles S rocking over angle bars 6. As the car is carried to its duni )ing po so By this locking I mechanism practically no eiiort is required i upon the part of the operator to unlock the car, and no danger due to accidents caused by forgethilness on the part of the operator to lock the car can occur. Furthermore, the .car body isunlocked by the operator from the side. opposite to that from which the dumping ta es lace so that there is no danger in the un ocking of the car body to the o erator. The lever when turned to its unloc ed position remains there so that the operator is able to use both his hands to dum the car. The locking mechanism is' siinp e in construction and not lia-ble to get Outo order.

By the use of thereycloidcurve -on the cradles I ain enabled'to build the'dunip car lower, While at the same time there is greater adjustability of the cradle to different sizes of car bodies. vBy changing the Y 'FTQ' "7' '899,108'-;
